Bigcountry is absolutely right-quantity does not add up to quality practice.You have to figure out what makes you inconsistant and work on that.If it's more than one problem area,work on one part until you get that proper form then move on to the next issue.Maybe you're overbowed,maybe the arrows aren't spined right for your bow.Your anchor could be inconsistant,a lousy release and follow-thru.etc.Watch the guy at the range that stacks them in there and don't be afraid to ask him to watch you shoot and let you know what's wrong.Once you put the pieces together,it's absolutely enjoyable each and every arrow
